Note Cards (10 Stunning Images)

GSA publications have sported stunning cover images over the years, and we have chosen 10 of them for these note cards. Images include a cross section of lodgepole pine; a shell bed with trilobites and brachiopods; eruption of Tungurahua volcano, Ecuador; honeycomb weathering of sandstones in Kenting National Park, Taiwan; and a backscattered electron image of omphacite decomposed to symplecite. Perfect for thank you notes and other times when an e-mail just won't do!
